4. Press the C - Key to make F3 non-latching. OR Press the T + Key to
make F3 a normal latching on/off function.
5. Press the EXIT Key to complete the set up of F3 as a non-latching
key.
This will cause the COUPLER 3 Key to operate Function 3 as a non-
latching function for this particular DCS50 and any attached Jump™
Throttles. Other throttles (including other DCS50s) in the system
will not be affected.
16.2 Function Operation Troubleshooting
If the function you want to operate does not respond, check the following:
1. Is TRACK STATUS on? If not press the POWER Key to turn it on.
2. Did you select the correct loco? If not, select it now.
3. Is the function you want to use installed in the loco? If not, you may
need to install it. When you purchase a new loco most come with a
head lamp installed, some have a back up lamp already installed but
most do not have any additional lights installed. If you want to use
the additional functions, you will have to install them in the loco.
4. Change the position of the DIRECTION LEVER and see if the lamp
comes on in the other direction. If the normal direction of travel fea-
ture in the decoder loco is set for the opposite of what you were
expecting, you will see the head lamp operating in what you expect-
ed to be the reverse direction and vice versa for the back up lamp.
See your Digitrax Decoder Manual for information about how to
change the Normal Direction of Travel.
16.3 Controlling Functions 9-12
The DCS50 alone is not able to control functions 9-12. You can use a
DT400 throttle with a DCS50 to access F9-F12.
17.0 MU (Multiple Unit) Operations
It is not uncommon to see two, three or even four diesel locos pulling in con-
sist at the front of a train. Sometimes, there is a locomotive added in the middle
of the train or at the end of the train to give “helper service” to the head end
locomotives. This is called Multiple Unit Operation or MU operation. With
DCC, each locomotive is separately controlled. But in the case of MU’ing we
would like to have more than one locomotive address controlled by a single
throttle to simplify MU operation.
